On my way to a 380 mile drive, a funny (understatement)thing happened to the cruise control and wiper of my 780 turbo. First, the cruise conrol; I had some difficulty engaging the cruise control. After a brief stop and restarting the car, the cruise control would either engage easily or it takes some few minutes of running before it would engage. Also, when I hit uneven road and the car would bounce up and down, the cruise control would automatically disengage.

Then, when it started to rain, I switched on the wiper to the intermittent speed and it just didn't work. I tried squirting some wiper fluid to entice the wiper work but it didn't. No wiper fluid and no intermittent speed function. However, if I move it to the slow and fast speed the wiper worked. I am puzzled on these two occurrences. Any ideas and help would greatly be appreciated. BTW, prior to this long journey, both cruise control and wiper were working normally. Thank you.
